Trying to calculate the amount of beer that will be consumed at our wedding. Bar hours will be from 12pm-4pm, roughly. So how much beer is appropriate for a wedding of 80 people? Only approximately half are beer drinkers. This is for a beer/wine bar only.

I would say 4 per beer drinker but also keep in mind some people who don’t normally drink will at weddings. I prefer to over-estimate just because I would rather have extra than run out. But since it’s 12-4pm I would imagine people wouldn’t drink as much as they would at night.

For a daytme wedding, the Real Simple wedding alcohol calculator recommends at a beer/wine/champagne bar there be 2 beers per person and a bottle of red, white, and champagne for every 3 or 4 people, so you would want something like

160 bottles of beer

25 bottles of champagne

25 bottles of red

25 bottles of white

If you aren’t having champagne, adjust to add a bit more beer and wine.

Keep in mind they are assuming a share of people won’t drink at all and some will only drink beer, others only wine.

FI said 7 or 8 for a 5 hour reception. He likes his beer. He said a little less since it is in the afternoon and only 4 hours. He is probablyone of the heaviest beer drinkers you would have there. I voted 6+, but I think it would probably average closer to 4. I would get enough for 5 per beer drinker since most people aim to drink one per hour and then you’ll have a little extra for the heavier drinkers.
